[PATCH v4 0/7] gc: tests and handle reflog expire config

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

It seems the list software dislikes Michael Haggerty for some reason,
but as seen in my reply to his message my v4 has some unaddressed
issues in the previous 8/8 that I need to get to:
https://public-inbox.org/git/87pnqkco8v.fsf@evledraar.gmail.com/

I'll have limited time next week to get to that, so in the meantime
here's a re-send without that patch, but just the unrelated
cleanup/tests & gc "expire" fix up to v3's 7/8. The only other change
is fixing commit message nonsense (from an earlier version), which
Peff pointed out.

I'll then get to the issue mhaggerty noted & submit that independently
later, but this should be ready for queuing & moving down to next,
since (unlike the previous 8/8) none of it's tricky code we need to be
really careful with.

Ævar Arnfjörð Bjarmason (7):
  gc: remove redundant check for gc_auto_threshold
  gc: convert to using the_hash_algo
  gc: refactor a "call me once" pattern
  reflog tests: make use of "test_config" idiom
  reflog tests: test for the "points nowhere" warning
  reflog tests: assert lack of early exit with expiry="never"
  gc: handle & check gc.reflogExpire config
